# 使用 Nginx 部署 使用 Nginx 在您自己的服务器上托管 BentoPDF。 ## 前置条件 - Ubuntu/Debian 服务器 - 已安装 Nginx - SSL 证书(推荐:Let's Encrypt) ## 步骤 1:构建项目 ```bash git clone https://github.com/alam00000/bentopdf.git cd bentopdf npm install npm run build ``` 如需自定义品牌,请在构建前设置环境变量: ```bash VITE_BRAND_NAME="AcmePDF" VITE_BRAND_LOGO="images/acme-logo.svg" npm run build ``` ## 步骤 2:复制文件 ```bash sudo mkdir -p /var/www/bentopdf sudo cp -r dist/* /var/www/bentopdf/ sudo chown -R www-data:www-data /var/www/bentopdf ``` ## 步骤 3:Nginx 配置 创建 `/etc/nginx/sites-available/bentopdf`: ```nginx server { listen 80; server_name your-domain.com; return 301 https://$server_name$request_uri; } server { listen 443 ssl http2; server_name your-domain.com; # SSL Configuration ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem; root /var/www/bentopdf; index index.html; # Gzip compression gzip on; gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/wasm; gzip_min_length 1000; # WASM MIME type types { application/wasm wasm; } # Required headers for SharedArrayBuffer (LibreOffice WASM) # These must be on every response - especially HTML pages add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; add_header Cross-Origin-Resource-Policy "cross-origin" always; # Security headers add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Content-Type-Options "nosniff" always; add_header X-XSS-Protection "1; mode=block" always; # Pre-compressed LibreOffice WASM binary location ~* /libreoffice-wasm/soffice\.wasm\.gz$ { gzip off; types {} default_type application/wasm; add_header Content-Encoding gzip; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # Pre-compressed LibreOffice WASM data location ~* /libreoffice-wasm/soffice\.data\.gz$ { gzip off; types {} default_type application/octet-stream; add_header Content-Encoding gzip; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # Cache static assets location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|wasm)$ { expires 1y; add_header Cache-Control "public, immutable"; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } # SPA routing - serve index.html for all routes location / { try_files $uri $uri/ /index.html; add_header Cross-Origin-Embedder-Policy "require-corp" always; add_header Cross-Origin-Opener-Policy "same-origin" always; } } ``` ## 步骤 4:启用站点 ```bash sudo ln -s /etc/nginx/sites-available/bentopdf /etc/nginx/sites-enabled/ sudo nginx -t sudo systemctl reload nginx ``` ## 步骤 5:使用 Let's Encrypt 配置 SSL ```bash sudo apt install certbot python3-certbot-nginx sudo certbot --nginx -d your-domain.com ``` ## 子目录部署 要托管在 `/pdf/`: ```nginx location /pdf/ { alias /var/www/bentopdf/; try_files $uri $uri/ /pdf/index.html; } ``` 构建命令: ```bash BASE_URL=/pdf/ npm run build ``` ## 性能调优 添加到 `nginx.conf`: ```nginx http { # Enable sendfile sendfile on; tcp_nopush on; tcp_nodelay on; # Increase buffer sizes client_max_body_size 100M; # Worker connections worker_connections 2048; } ``` ## 故障排除 ### WASM 无法加载 确保已设置 MIME 类型: ```nginx types { application/wasm wasm; } ``` ### 签署 PDF 或 Form Filler 显示空白查看器(`.mjs` MIME 错误) 如果浏览器控制台显示: ``` Failed to load module script: The server responded with a non-JavaScript MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec. ``` ……并且失败的请求以 `.mjs` 结尾,说明您的 nginx 缺少 `.mjs → application/javascript` 的映射。内置的 PDF 查看器(签署 PDF、Form Filler 和其他一些工具使用)附带扩展名为 `.mjs` 的 ES 模块文件,而 nginx 默认的 `mime.types` 不包含它们。 解决方法:在 `/etc/nginx/mime.types` 中,将 `mjs` 加到现有的 `application/javascript` 行: ```nginx application/javascript js mjs; ``` > 请勿再追加*第二行* `application/javascript`。nginx 逐行解析 `mime.types`,每种类型只有一个扩展名映射生效,因此在某些版本中第二行会被静默忽略。请编辑现有的行,把 `mjs` 与 `js` 放在一起。 或者在您的 server 块内局部覆盖(无需修改全局文件): ```nginx types { application/javascript js mjs; application/wasm wasm; } ``` 修改后重新加载 nginx: ```bash sudo nginx -t && sudo systemctl reload nginx ``` 确认方法:在浏览器开发者工具的 Network 标签中,找到失败的 `.mjs` 请求并检查 `Content-Type` 响应标头。它现在应为 `application/javascript`,而不是 `application/octet-stream`。 ### Word/ODT/Excel 转 PDF 无法使用 LibreOffice WASM 需要 `SharedArrayBuffer`,而这需要 `Cross-Origin-Embedder-Policy` 和 `Cross-Origin-Opener-Policy` 标头。它还需要安全上下文,因此 `http://localhost` 可用于本地测试,但 `http://192.168.x.x` 或其他局域网 IP 通常需要 HTTPS。请注意,`location` 块中的 nginx `add_header` 指令会**覆盖**server 级别的 `add_header` 指令,而不是合并。每个带有自己 `add_header` 的 `location` 块都必须包含 COEP/COOP 标头。 验证方法: ```bash curl -I https://your-domain.com/ | grep -i cross-origin ``` 如果 nginx 前面有反向代理,请确保它保留这些标头。 ### 502 Bad Gateway 查看 Nginx 错误日志: ```bash sudo tail -f /var/log/nginx/error.log ```
